It is designed to create a fixed standoff gap between a printed circuit board and a mounting surface, maintaining proper clearance and reducing vibration contact. With an overall length of 1.5 inches, an inside diameter of 0.171 inches, and an outside diameter of 0.3125 inches (5\/16 inches), this spacer is sized for No. 8 screw hardware. It meets fastener standard QQ-A-225A Comp 2 and ships uncoated. Electronics assemblers, HVAC control board technicians, and electrical panel builders commonly install this type of hardware during board mounting and service.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and light commercial applications wherever a printed circuit board requires a rigid, non-threaded standoff. Typical use cases include mounting control boards in HVAC equipment, electrical enclosures, and industrial panel assemblies. The aluminum construction keeps weight low while providing adequate structural support. It is sold individually and is compatible with No. 8 screw installations requiring a 1.5-inch standoff height.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 8 screw hardware for secure board mounting\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.5 inches provides consistent standoff clearance\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.171 inches with a tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.3125 inches (5\/16 inches) for compact footprint\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T-3 construction per fastener standard QQ-A-225A Comp 2\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; suitable for standard indoor electronic assembly environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in No. 8 screw circuit board mounting applications requiring a female unthreaded round spacer with a 1.5-inch standoff length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and de-energize all circuits before handling or replacing circuit board hardware. This spacer is installed by electronics assemblers or qualified technicians using standard hand tools. Verify screw size and board hole dimensions before installation to ensure proper fit. Avoid over-tightening fasteners through the unthreaded bore, as this can crack the board or deform the spacer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.171 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S873-MO4-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739972272434,"sku":"S873-MO4-F16-H","price":23.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_be28736a-2a43-4e9b-b2c3-7ebdec57f3b1.jpg?v=1788820912","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s873-mo4-f16-h-round-board-spacer-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
